Thanks fdegrove! I went with the 9s jockey to have more clearance like on the 10 speed carbon derailleur. 8.9mm instead of 8.4mm. Some said that the 10 speed chain would rub sometimes on the SR derailleur. When I try an 11s chain, i'll put back everything to 11s spec.

With an 11 crank I'd suggest an 11 chain due to external clearance for the chain when in the small chainring and smaller cogs. But then if you go with the 11 chain you will want an 11 front der also - as a added width "slop" of a 10 frt der combined with tighter setup of the crank you won't get as clean front shifts with the 10 frt der.

So one option is try the 10 chain and frt der and if you're ok with clearances on the chainrings then go for it.
